The subsections represent the individual census tracts within the selected jurisdiction. For example, Baldwin County has 9 census tracts. This allows you to view the SVI variation within the jurisdiction. The 2010 SVI maps are delineated according to the 2010 Census tract reference maps (https://www.census.gov/geo/maps-data/maps/2010tract.html).

Data for maps originates from the CDC, http://svi.cdc.gov, and is adapted for local planning. This data is collected by the U.S. Census (2000 and 2010) and the American Community Survey (2006-2010). Specifically, for 2000 data, the maps use variables found in SF1; and, for 2010 data, five (5) variables from the U.S. Census SF1 and nine (9) variables from 2006-2010 American Community Survey.

Each tract is ranked according to its level of vulnerability in comparison to all other tracts for the specified area (state, region, county, etc). Tracts are ranked in a range from zero (0) to one (1), with higher values indicating greater vulnerability. The percentile ranking is the rank of a value as a percentage of the data set. Census tracts are ranked to enable mapping and analysis of relative vulnerability across multiple planning and preparedness jurisdictions, including state, regional, and county-level areas.

Disability data, which were included in 2000 U.S. Census, were not collected at tract level for either 2010 U.S. Census or the American Community Survey (ACS). The remaining 14 variables are used to calculate the 2010 tract level data from the U.S. Census (SF1) and the American Community Survey (ACS).
